LESSONS IN LEADERSHIP:  The Quest for Truth reveals the lessons of motivation, passion, team building, and leadership via the tales of a fictional character.  The book chronicles the allegorical journey of Youngblood Hawke as he is transformed from a self-serving soldier of fortune to a warrior prince. Presented with the question and challenge of absolute truth by a mystical sage, Hawke's inability to respond is an epiphany to him and marks the beginning of his struggle and quest. Guided by a beautiful oracle, he is introduced to the teachings of Socrates, Plato, Aristotle, Sun Tzu, Machiavelli, Nietzsche, Jose Ortega, Shakespeare, and William James spoken through mentors, sages, and prophets. Marked as a threat to their power and control over humanity, the enemies of change seek to destroy him and his desire to understand. Youngblood Hawke's destiny as a warrior prince is realized when he raises an army of "Select Warriors" and leads them against the "mass," a secret and powerful society controlling many of the world's governments. Youngblood Hawke quickly learns that the spiritual and philosophical battle for truth will not only be waged on the battlefield but also within the darkest confines of the human mind, heart, and soul.  THIS IS A MUST READ FOR THE PROFESSIONAL WITH THE HEART AND SOUL OF A WARRIOR!

Published: February 09, 2011 by CRC Press - 382 Pages Authored By: Dean A. Beers, CLI, Associates in Forensic Investigations, LLC, La Porte, Colorado, USA


- Presents a system that is easily adaptable to small assignments as well as complex litigation cases.


- Emphasizes preparation, the most often neglected aspect of many investigations


- Differentiates between conducting and completing assignments and investigations


- Provides protocol for fact acquisition, recording, communicating, and reporting


Legal investigators are responsible for providing factual evidence – as the fact finders, they are the foundation for the attorneys they work with daily. The attorney is responsible for forming and implementing the legal strategy and presenting it to the judge or jury. The legal investigator provides checks and balances to ensure that no evidence is being forced upon a theory, and that no theory is being forced upon the evidence. Practical Methods for Legal Investigations: Concepts and Protocols in Civil and Criminal Cases presents legal investigators with a step-by-step process that reveals how to methodically find and report evidence in every aspect of the investigative process.


Similar to the scientific principle of using research to prove or disprove a theory, the author’s Investigative Protocol is designed to find the facts that prove or disprove criminal charges, civil allegations, or elements thereof. The book includes case studies that clearly detail how the process of the Investigative Protocol applies to every assignment of the case and to the case as a whole. Comprehensive and methodical, the system provides a map to the truth.
